a simple class to control print indentation
Definition: vtkIndent.h:34
Key for double values in vtkInformation.
Key for integer values in vtkInformation.
vtkViewNode specialized for vtkLights
Definition: vtkLightNode.h:29
a virtual light for 3D rendering
Definition: vtkLight.h:57
links vtkLights to OSPRay
static double GetRadius(vtkLight *)
static vtkInformationDoubleKey * RADIUS()
The radius setting, when > 0.0, produces soft shadows in the path tracer.
static int GetIsAmbient(vtkLight *)
static void SetLightScale(double s)
A global multiplier to all ospray lights.
static vtkOSPRayLightNode * New()
virtual void Render(bool prepass) override
Make ospray calls to render me.
static vtkInformationIntegerKey * IS_AMBIENT()
When present on light, the light acts as an ambient source.
static void SetRadius(double, vtkLight *)
Convenience method to set/get RADIUS on a vtkLight.
~vtkOSPRayLightNode() override
static void SetIsAmbient(int, vtkLight *)
Convenience method to set/get IS_AMBIENT on a vtkLight.
static double GetLightScale()
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
